为了探索鸭稻共作技术在东北冷凉地区的可行性,本文在新宾县永陵镇郝家村试验研究了该技术对水稻生长性状和经济效益的影响.研究结果表明,鸭稻共作能促进水稻植株生长,增加有效分蘖,进而增加水稻产量,提高经济效益.鸭稻共作与普通插秧相对比,分蘖末期水稻株高提高8.83％;孕穗期,地上生物量、地下生物量、有效分蘖率分别提高9.59％、17.74％、25.4％;水稻单位面积穗数提高3.96％,每穗粒数增加1.04％,瘪粒率降低8.89％,千粒重提高3.03％;在同为22％含水率条件下,鸭稻共作技术的水稻产量为9003.37kg/hm2,比普通插秧的水稻产量提高了8.67％.在不施用肥料和除草剂的条件下,鸭稻共作技术生产有机稻米与普通插秧技术生产普通稻米相比较,可增加纯收入30477.47￥/hm2.研究成果为该技术在辽宁地区生产有机稻米、增加农民收入提供技术支持.

为了解黑龙江省直播稻的发展状况,根据生产调研,论述了黑龙江省水稻直播栽培技术的应用现状和成因,总结了直播稻发展中存在的问题,提出了水稻直播栽培技术发展的建议和对策,即加强水稻直播高产配套技术研究及水稻直播技术的引进和示范.现阶段的水稻直播栽培技术是在目前特定生产条件下形成的新的种植方式，具有劳动工效高、生产成本低等优点，但也存在直播稻主导品种不明确、主推技术不配套、病虫草害防治技术不到位等问题。
